4-2-8 Note for using the PTC-Starter / Combo
(1) Be careful not to allow over-voltage and over-current
(2) Do not drop or handle carelessly.
(3) Keep away from any liquid.
If liquid such as oil or water enters the PTC/Combo,
PTC/Combo materials may fail due to breakdown of their
insulating capabilities.
(4) If the exterior of the PTC/Combo is damaged, the
resistance value may be altered. This can cause damage to
the compressor and result in a no-start or hard-to-start
condition.
(5) Always use the PTC/Combo designed for the compressor
and make sure it is properly attached to the compressor.
Parts may appear physically identical but could have different
electrical ratings. Replace parts by part number and model
number. Using an incorrect part could result in damage to the
product, fire, injury, or possibly death.

bimetal wors by heating the heater inside the OLP, and the
OLP protects the motor by cutting off the current flowing to
the compressor motor.
